20th Annual Mole Day

Friday was the CHS AP Chemistry classes' annual recognition of Mole Day (actually Mole Day eve since Mole Day is Oct. 23).  Here is a brief explanation and of the day and activities from Mr. Dave Scott:

Celebrated annually on October 23 from 6:02 a.m. to 6:02 p.m., Mole Day commemorates Avogadro's Number (6.02 x 10²³), which is a basic measuring unit in chemistry.

When the atomic masses shown on the periodic table are expressed as grams, the number of atoms present are equal to                                     6.02 x 10²³ atoms (or 1 mole).

Mole Day was created as a way to foster interest in chemistry.  Schools throughout the United States and around the world celebrate Mole Day with various activities related to chemistry and/or moles.   Mole Day, 2010 is the 20^th annual National Mole Day.

At Celina High School, Mr. Scott’s AP Chemistry class traditionally celebrates Mole Day with liquid nitrogen demos performed by

Mr. Scott, along with decorations, food, and music.
